Seedream 4.0 is ByteDance's text-to-image model, rendering one image from a prompt. You choose the exact size from sixteen width*height presets, from 1024*1024 up to 4096*2304, at the same per-image rate for every size. Uncensored.

Outputaurora-ice-palace-glance `prompt` sets a large scene around a single figure, and everything it lists is in the frame: a hall of carved ice with translucent columns, ice swans, a prancing ice horse and a line of ice dancers, icicles and an ice chandelier hanging from arches open to the night sky, and emerald and violet auroras reflected in the polished floor. In the middle, a woman in a pale ice-blue satin gown with a low open back stands with her back to the camera, a white faux-fur stole over one shoulder and trailing down her arm, and looks back at the lens with a closed-lip smile. `size` is the default `2048*2048` square, which costs the same as every other preset on this endpoint.

Outputdragon-perch-4k `size` is `4096*2304`, the widest of the sixteen presets, and the brief is written to need it: a whole company strung along a cliff ledge, each figure carrying its own harness detail, with one wing shadow sweeping across all of them. At smaller presets a line-up like this collapses into texture. Storm light behind keeps the row separated in depth rather than flattened into a frieze, which is the thing worth checking at full size.

Outputwindow-light-boudoir A square 2048*2048 window-lit portrait: fabric, light direction, palette and lens are all named, so the brief decides the mood instead of leaving it to the model.
- 2048*2048
Outputneon-rooftop-wide A 4096*2304 wide frame with the subject staged across the width. It costs the same as the square example, and the brief ends by ruling out lettering, which neon-city prompts otherwise tend to invent.
